Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1065, check with Delta Air Lines.
DL 1065 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land roughly 50 minutes behind schedule. That rests on 286 flights, with a median arrival right on schedule.
The national on-time rate over the same period is 77.6%, so DL 1065 runs 6 points behind the country as a whole. Across a thousand flights that is about 64 extra late arrivals.

These figures cover 286 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.
Schedule
When DL 1065 flies
DL 1065 flies ATL to PBI without a single fixed slot. Its most common scheduled departure was 20:32, used on 40 of 286 flights, with 22:59 (40 flights) and 21:20 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 20:32 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1065 runs level with that at 71.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
DL 1065 next to ATL to PBI

Across the year
DL 1065 quarter by quarter
DL 1065 did not run the same all year. Its best quarter was Jan–Mar 2026 at 80.4% on time and its weakest Oct–Dec 2025 at 62.3%, a swing of 18 points on roughly 72 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202570 flights62.3%
- Jan–Mar 202658 flights80.4%
- Apr–Jun 202691 flights77.5%
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1065 did best on Monday at 80.0% on time and worst on Sunday at 57.8%. Each day rests on about 41 flights, so a gap of 22 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1065 runs late
One category carries most of the weight here. Carrier accounts for 53% of the 4,229 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 53%Carrier
- 27%Late-arriving aircraft
- 11%Extreme weather
- 9%National Airspace System
- 1%Security
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,221 of the 4,229 delay minutes reported here. The split is drawn from 4,229 delay minutes reported on DL 1065.
Cancellations sit at 1.75% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
The 545 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on two other city pairs in the data, including CHA to ATL (8) and ATL to CHA (8), but none flew often enough under DL 1065 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to PBI only.
One caution: this is a thin sample. 286 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking DL 1065
For a booking, read DL 1065 as 71.2% on time with 1.75% cancelled over 286 flights. Those are rates from the past twelve months, not a forecast for any particular day.
